Predict the Output and Evaluate your skills in Python
Want to be a Python expert by any chance? Well, with this article, you can learn how to create and understand tricky Python programs with ease. You’ll also find out how to become a pro in this language in no time. Follow along with the 10 programs we provide below and see your skills increase day by day!

1) Find the number in a list: The problem is that there may or may not be numbers within the list. If there are numbers, it will give their position starting from 0. If there aren’t any numbers on the list but other strings like “a” or “b”, it will say “List contains nothing.”
Example: List contains nothing.
2) Find the number in a dictionary: This problem is just like the previous one, but instead of numbers, it checks for any associated keys. If there are no keys associated with that value, it will return “Dictionary contains nothing”. If there are keys associated, it will return their position starting from 0.
Example: Dictionary contains nothing.
3) Split a string into an array and a list: splitString creates an empty list and an empty array when there are no delimiters to split other than ‘.’ or ‘;’. An empty string is considered as a single character and so will be split across single-character delimiters.
Example: splitString(‘hello world’.split(), [‘hello’, ‘world’]); produces [“hello”, “world”]
4) Split a string up using regular expression. Regular expressions are powerful tools to find and extract information from the string. They are usually simpler than look-ahead search (like grep or find) and often loop more efficiently, so they make a good choice if you’re working with huge amounts of data or need to do multiple passes over the string when processing large objects.
5) Match whether a pattern is present in a list or not: if it doesn’t match, it will return False; otherwise, it will return True.
6) Find the first position of a specific character or pattern in a list. If the character/pattern is not present, it will return -1.
7) Find the last position of a specific character or pattern in a list. If the character/pattern is not present, it will return -1. For example, if it finds “a” at index 4 and then “b” at index 7, it would return 7 because that’s the last index of any “b” in the list.
8) Remove an element from a list if its value matches another value: to be truly efficient, you should use .remove() instead of del.
9) Palindrome Number Checker This program checks if a given number is a palindrome or not. The term palindrome is used to denote a single-digit or an integer string (digits separated by spaces) which reads the same way backward and forwards.
For example, number 35472 is not a palindrome because it does not read the same way backward and forwards. On the other hand, number 363 reads the same way in both directions, and hence it is a Palindromic number. The program above reads the number and checks if it is palindromic. If it is palindrome then it prints “Yes” and if not then it prints “No”.
10) Binary Search Fibonacci Printer In this project, we try to print the Fibonacci Sequence of numbers by using a binary search technique. The sequence starts from 0 (zero) and each number after the first is described by a pair of the previous two numbers since zero is not a good choice for numbering from one to one hundred! The code works on a single integer variable named Fibonacci. This variable contains two strings: Fibonacci 0 and Fibonacci 1. It searches the current element in the given sequence and prints it if it is a Fibonacci number.
As a developer, you know that the more skills that you have, the better you can be at your job. But coding is often seen as a daunting skill because it can take years before someone becomes good at it. With this blog post, We had discussed and helped ease some of that anxiety by showing 10 tricky Python programs for intermediate developers. If you want to know more you can check out the python developer training for beginners and advanced learners. Hope you’ve enjoyed this post.
